I'm new here, so this will be my introduction, and hopefully a good explanation of my car/project. I'll try to keep it up to date as others have done.
So, here is my car:
It is a USDM 1994 Nissan Sentra SE-R. I've taken the modification road that I think most people recommend, but rarely follow.
I upgraded brakes first:
Front:
Rear:
Needed new wheels to clear the brakes, so they went on too:
I then moved to suspension, installing 3-way adjustable sway bars, rear tower brace, and I have stiffer spring/dampers on the way. (Sorry, no good pictures.)
The battery moved to the trunk in anticipation of turbo, and for better weight distribution:
Notice external cut-off switch:
Now I'm finally on to the power (it's been four years since I started, continually being plagued by money issues). The money problem is no more, so it is time for a turbocharger. For those of you not familiar with these cars, the SE-R model came with the USDM SR20DE motor (also used in the USDM Infiniti G20). This is the detuned N/A version of the beloved SR20DET motor everyone is so keen on. After scratching the idea of turbo-ing my motor, I've decided to drop in a JDM SR20DET, trying to keep the cost and hassle down to a minimum. This is where VEMS comes in. I've decided against the typical JWT ECU. It would be a good choice, but I want to learn engine management, and I'm taking this chance to do just that.
EDIT Sep, 2007: I found out my stock motor is good for 350-400 HP on stock internals, so I've decided to just turbo my stock motor instead of doing a motor swap and take advantage of the better off-boost throttle response from the higher compression ratio (9.5:1 vs. 8.5:1).The plan is to equip my N/A car with VEMS, get it working to stock or better performance, economy, etc. and learn what I have to learn about tuning an N/A motor. I will then drop in the turbo motor, and be in a good position to extract the amount of power that I'm looking for with general ease.
I've done my homework, and it seems I have two or possibly three major questions right now.
What do I have to do to buy VEMS, and whom/where should I buy it from?
What do I need to do about the Nissan trigger situation, and where can I get a machined cam angle sensor disc? (Should I do a crank angle sensor as well?)
Where do I get one of those wonderful VEMS to Nissan factory harness adapters I've seen pictures of, and which one will work with the car with the least re-wiring?
Let the party begin,
